A simple and quick linear switching clamp.

Three M4x25-35mm-long bolts and nuts are needed, as well as one M6 bolt and nut for convenient adjustment of the end.

In order to increase the strength of the parts, we can add more walls.

I added some glue to the end of the switching pin.

The push block is just loosely fitted, and we may choose a different material in the future.

I choose not to add a handle, but I can fix it in place with glue.

With an approximate stroke of 30mm.
